Note that you need to list the less specific "qcom,adreno" (since this

is what the device is matched on), in addition to the more specific

|

- reg: Physical base address and length of the controller's registers.
|

- interrupts: The interrupt signal from the gpu.
|

- clocks: device clocks
|

See ../clocks/clock-bindings.txt for details.
|

- clock-names: the following clocks are required:
|

* "core_clk"
|

* "iface_clk"
|
||||
* "mem_iface_clk"
|

- qcom,chipid: gpu chip-id. Note this may become optional for future

devices if we can reliably read the chipid from hw
